Installation Guide

The installation of this Vent to Atmosphere Chassis Kit requires minimal mechanical knowledge and tools. It is important to follow these instructions.


  • M8 x 1.25 Tap
  • Allan Key set
  • Knife to cut silicone pipe
  • Silicone sealant (optional)


  1. The T-Fitting supplied has 1 end blocked, this is to be used in the orginal pipe from the pcv valve in the rocker cover to the intake pipe. The blocked end faces towards the intake while the other two ends are to divert the flow away from the intake and out to the Y-Piece.Vent to Atmosphere Chassis Kit
  2. Using the supplied silicone pipe, join the T-Piece and the Y-Piece together, the Y-Piece is to evenly split the flow either side of the bell housing then to the chassis rail fittings.Vent to Atmosphere Chassis Kit
